 * Implementation of the <b>Manager</b> interface that makes use of a Store to

 * different goals:
 * 
 * <li>Persist sessions across restarts of the Container</li> <li>Fault
 * tolerance, keep sessions backed up on disk to allow recovery in the event of
 * unplanned restarts.</li> <li>Limit the number of active sessions kept in
 * memory by swapping less active sessions out to disk.</li>
